摘　　要：目的明确SARC-F量表及其改良版作为社区老人肌少症评估工具的筛查和诊断价值。方法以亚洲肌少症工作组(AWGS)肌少症诊断标准为金标准,采用ROC计算改良版最佳截点,通过四格表数据计算SARC-F量表及其改良版的敏感度、特异度、阳性预测值(PPV)、阴性预测值(NPV)及准确度。结果SARC-F改良版最佳截点为2.5分,原版和改良版诊断敏感度分别为1.18%、23.53%,特异度分别为99.05%、82.97%,PPV分别为12.5%、13.7%,NPV分别为89.72%、90.43%,准确度分别为88.97%、76.85%。结论SARC-F在社区老年人肌少症筛查诊断中有一定的价值,但仍需开发敏感度更高的筛查工具,减少漏检的发生。Objective To clarify the screening and diagnostic value of SARC-F scale and its improved version as a tool for evaluating sarcopenia in the elderly in the community.Methods The Asia Working Group for Sarcopenia(AWGS)diagnostic criteria for sarcopenia was used as the gold standard.The receiver operating characteristic curve was used to calculate the optimal cut-off point of the modified version.The sensitivity,specificity,positive predictive value(PPV),negative predictive value(NPV),and accuracy were calculated using four grid table.Results The cut-off point of the improved version of SARC-F was 2.5.The diagnostic sensitivitiy of the original version and modified version was 1.18%and 23.53%,the specificity was 99.05%and 82.97%,PPV was 12.5%and 13.7%,NPV was 89.72%and 90.43%,and the accuracy was 88.97%and 76.85%respectively.Conclusions SARC-F has certain value in screening and diagnosing sarcopenia in the elderly in the community,but it is still necessary to develop more sensitive screening tools to reduce the incidence of missed diagnosis.
